Strategies For Improving Oxygen Transport And Mechanical Strength In Alginate-Based Hydrogels, Joseph C. White
Strategies For Improving Oxygen Transport And Mechanical Strength In Alginate-Based Hydrogels, Joseph C. White
Doctoral Dissertations
Hydrogels have attracted significant interest over the past several decades due to their outstanding versatility as biomaterials. Alginate-based hydrogels are among the most popular studied due to their low cost, biocompatibility, and tunable physical properties. However, as with all hydrogels, persistent oxygen solubility and poor mechanical strength limits their utility for creating macroscopic devices for biomedical use. This thesis presents two strategies for improving oxygen transport and mechanical properties of alginate-based hydrogel. The former involves incorporating perfluorocarbons, hydrophobic compounds with very high oxygen solubility, into the formulation. The perfluorocarbons are stabilized by nonionic surfactants, Pluronics®, and the emulsion is entrapped …
